Some 480,000 children under five die each year of diarrhoea, more than half of these directly linked to poor water, sanitation and hygiene.
And 880,000 children under five die each year of pneumonia – which also has links to dirty water, poor sanitation and poor hygiene.
Far too many children are deprived of these, affecting their health, education and life chances.
The greatest tragedy of all is that we know how to address this - .deliver clean water and hygenic sanitation to everyone. Ensuring 100% coverage with water, sanitation and hygiene, rotavirus vaccination and nutritional interventions such as breastfeeding promotion and zinc supplements could potentially reduce illness by nearly two thirds (63%) and almost halve the number of child deaths (49%) from diarrhoea and pneumonia. None of this requires new technology or invention.
